Abstract: This sero-survey describes the level and time-trend of antibodies elicited by BNT162b2 COVID-19 vaccine up to 6 months. A strong seroconversion was seen at 30-day serology, with persistence of anti-SARS-CoV-2 S-RBD IgG through 6 months from vaccination. However, the level of vaccine-induced antibodies started to decrease from the second month.
